: Numerous studies have demonstrated the safety and efficacy of intraarticular stem cell injections for treating osteoarthritic knee joints, reporting symptom reduction and pain relief within a few months of treatment. Here, we report the results of a 7-year follow-up after a single intraarticular injection of 0.5-1 × 10 autologous adipose tissue-derived mesenchymal stem cells in patients with OA (Kellgren-Lawrence grade 2 to 4).

There is still limited understanding of the microstructural reasons for the higher susceptibility to fractures in individuals with type 2 diabetes mellitus (T2DM). In this study, we examined bone mineralization, osteocyte lacunar parameters, and microhardness of the femoral neck trabeculae in 18 individuals with T2DM who sustained low-energy fracture (T2DMFx: 78 ± 7 years, 15 women and 3 men) and 20 controls (74 ± 7 years, 16 women and 4 men). Femoral necks of the T2DMFx subjects were obtained at a tertiary orthopedic hospital, while those of the controls were collected at autopsy.

The cementless Corail stem is one of the most frequently implanted stems and has undergone several design changes. Currently in use is the third generation, named Corail AMT. Until now, only one third-generation Corail stem neck fracture has been described in 2020.

Article Synopsis
  • The study aimed to investigate the shapes of the first metatarsal-cuneiform (MTC) joint in feet with hallux valgus (HV) deformity and how these shapes relate to angles associated with HV.
  • Researchers analyzed the shapes in a sample of 315 feet and found that the oblique shape was most common, often linked with more severe forms of HV.
  • The results indicated that the shape of the first MTC joint significantly influences the hallux valgus angle (HVA), while the intermetatarsal angle (IMA) did not show a statistically significant relationship with the joint shape.

Background: Perthes disease is a juvenile form of osteonecrosis of the femoral head that affects children under the age of 15. One hundred years after its discovery, some light has been shed on its etiology and the biological factors relevant to its etiology and disease severity.

Methods: The aim of this study was to summarize the literature findings on the biological factors relevant to the pathogenesis of Perthes disease, their diagnostic and clinical significance, and their therapeutic potential.

Individuals with diabetes mellitus type 2 (T2DM) have an increased risk of hip fracture, especially if vascular complications are present. However, microstructural origins of increased bone fragility in T2DM are still controversial. DXA measurement of the contralateral hip and three-dimensional microCT analyses of femoral neck trabecular microarchitecture were performed in 32 individuals (26 women and 6 men, 78 ± 7 years).

To examine the influence of the configuration of the first and second metatarsal (MT) bones on the development of hallux valgus deformity. To determine the extent to which the difference in the lengths of the first and second MT bones, measured distal to the Maestro line, contribute to the severity of the hallux valgus (HV) deformity defined by the size of the hallux valgus angle (HVA) and inter-metatarsal angle (IMA). On a sample of 319 feet with HV deformity the difference of measured lengths R = d (I MT) - d (II MT) was calculated The influence of differences (R) on the values of IMA and HVA as well as on the severity of deformities according to the formed groups was investigated.

Introduction: Split tendon transfer of tibialis posterior (SPOTT) is a treatment option for the hindfoot varus deformity in patients with cerebral palsy (CP). The purpose of this study was to present the long-term results of the newly modified SPOTT procedure developed by our senior author and compare it with the standard SPOTT technique in equinovarus foot deformity due to CP.

Method: Our retrospective cohort study included patients with spastic foot deformity due to CP treated with the standard or modified SPOTT technique.

The purpose of this work is to develop a new model estimate of the fatigue life of a hip prosthesis due to aseptic loosening as a multifactorial phenomenon. The formula developed here is a three-parameter model based on Basquin's law for fatigue, eccentric compression formula for the compressive stress and torsion in the prosthesis due to the horizontal components of the contact force. With our model, we can accurately predict the durability of a hip prosthesis due to the following four parameters: body weight, femoral offset, duration, and intensity of daily physical activities of a patient.

Background: Osteoarthritis (OA) is a chronic degenerative joint disease and is considered to be the fourth leading cause of disability and the second cause of inability to work in men. Recently, adipose-derived mesenchymal stem cells (AD-MSCs) came into focus for regenerative medicine as a promising tool for the treatment of OA. The administration of stem cells into impaired joints results in pain relief and improves quality of life, accompanied by restoration of hyaline articular cartilage.

Unlabelled: Perthes disease is one of the most common forms of pediatric femoral head osteonecrosis with an unknown etiology. Coagulation factors were the first genetic factors suspected to have a role in the pathogenesis of this disease, but studies showed inconsistent results. It is described that inflammation is present during early stages of Perthes disease, but its genetic aspect has not been studied extensively.

Introduction: Perthes disease is idiopathic avascular osteonecrosis of the hip in children, with unknown etiology. Inflammation is present during development of Perthes disease and it is known that this process influences bone remodeling.

Objective: Since genetic studies related to inflammation have not been performed in Perthes disease so far, the aim of this study was to analyze the association of frequencies of genetic variants of immune response genes, toll-like receptor 4 (TLR4) and interleukin-6 (IL-6), with this disease.

Purpose: The aim of this study was to evaluate whether ultrasound sonography (USS) performed by orthopedic surgeons is a reliable method of investigating lateral meniscus (LM) knee lesions as compared to magnetic resonance imaging (MRI), and arthroscopy, which is the gold standard in clinical practice.

Methods: In total, 107 patients were involved in this study. They were hospitalized for arthroscopy due to LM injury of the knee.

Total hip arthroplasty is most common reconstructive hip procedure in adults. In this surgery we replace some parts of the upper femur and acetabulum with biocompatible materials. The main goal of this surgery is to eliminate pain and regain full extent of joint motion, maintaining hip stability.

During the period of development foot deformities can occur, not only during the growth and development, but also in the later age. The most frequent foot deformity is flatfoot, congenital club foot and hallux valgus. Prior to the decision on surgical treatment of the deformity, whenever possible the patient should be referred for physical therapy that may yield acceptable results in specific treatment phases.

Hallux valgus is a complex deformity of the forefoot. Beside the lateral deviation of the first metatarsophalangeal joint angle exceeding 15-20 degrees and intermetatarsalvarus exceeding 8-9 degrees, it is also characterized by extensive changes of the soft tissue arch, sesamoid mechanism and metatarsocuneiform joint. It occurs almost exclusively in humans wearing shoes.

Clubfoot, or talipes equinovarus, is a deformity consisting of equinus, varus, and adductus foot deformity. The true etiology of congenital clubfoot is unknown; several theories have been proposed. The pathology of the individual bones contributes to the clubfoot deformity and soft tissue contractures around the ankle and talocalcaneonavicular joint maintains the deformity and involve muscles, tendons, tendon sheaths, ligaments and joint capsules.

Feet are maybe the key part of our musculoskeletal system that establishes upright position and movement. Their role is multiple--they maintain the balance of the body, push the body forward when walking and absorb mechanical pressure created in contact with the surface. Therefore, correct anatomic and functional development of foot is of vital importance.
